Keep in mind, the "other pc" that I have is a P4 from ten years ago.... can't exactly pop the cpu chip in there and check it out. The optical drive, ssd, and hdd aren't connected when I get the issue, so it should not be those. The memory and cpu can't be used in the old computer. I doubt it's the power supply based on the nature of the problem.

I suppose I could try my video card in the old computer. Would a Radeon HD 5970 even run on a computer that old? Perhaps that was before the invention of the PCIe slot....
